Abstract
An automatic water drain apparatus includes a reservoir, a fluid inlet, and a fluid outlet. A first valve member is moveable between an open position for admitting fluid to the reservoir via the fluid inlet and a closed position for preventing admission of fluid to the reservoir. A second valve member is moveable between an open position for exhausting fluid from the reservoir and a closed position for preventing exhaust of fluid from the reservoir. At least one actuator is operable to move the fluid inlet and the fluid outlet between their respective open and closed positions. A sensor is disposed outside the reservoir and is operable to produce a first sensor output signal in response to detection of the presence of water, wherein the at least one actuator moves the first valve to the open position in response to the first sensor output signal.
